Default Bookcase fields for a video

I’m trying to settle on the default fields for the video collection. I figure it will be mostly used for DVDs and maybe videocassettes, but I don’t want to limit it too much. Right now, my default fields are:

Title

Medium – DVD, VHS, VCD, or DivX

Year – production or release year

Format – PAL, NTSC, or SECAM

Genre

Region – DVD Region Encoding

Nationality – country of release

Rating – G, PG, PG-13, or R

Cast – a 2-column table for the actors and their roles

Director

Producer

Writer

Composer

Studio

Language Tracks – audio language tracks

Subtitles – subtitle languages

Audio Tracks – I need a better title for this – it’s for DTS, Dolby, etc.

Runnning Time – A numerical entry, running time in minutes

Color – color or b&w

Other Features – things like music videos, deleted scenes, etc.

Widescreen – a checkbox

Director’s Cut – a checkbox

Plot Summary – a textbox

Personal Rating

Purchase Date

Purchase Price

Gift – a checkbox

Loaned – a checkbox

Of course, the user is free to add, modify or delete fields however they want. The default fields will be the ones that get translated, though, so I want to have a good set. I’ve looked at several other DVD Collection applications and these seem to be the common set of fields.
